Roofs in Centro Habana: Improvisation as a Building Method
Centro Habana is a neighborhood that doesn’t exist in architecture textbooks. There are no projects signed by industry stars, no standards or certification processes. Instead, there’s something rarer: a building system that works without instructions, without spatial development plans, and often without permits. This is a place where roofs are born from necessity, and their form results from available materials, the owner’s skills, and whatever the sea has brought or a neighbor has left behind.
A walk through Centro Habana is a lesson in survival architecture. Roofs here aren’t designed—they’re added, repaired, improvised. And that’s precisely why they deserve attention. They show how flexible construction can be when the system is absent, but the need remains.
Where Concrete Meets Corrugated Metal
Centro Habana lies between the Old Town and the Vedado district—geographically central, symbolically peripheral. Buildings were constructed mainly at the turn of the 19th and 20th centuries, when Havana was one of the region’s wealthiest cities. Today these same tenements stand in various stages of decay. Facades fall off in sheets, balconies are propped up with wooden beams, and roofs—flat, designed for a frost-free climate—leak after every downpour.
Owners don’t wait for renovations. They build themselves, often without permission, sometimes without the knowledge of neighbors on lower floors. The result? Centro Habana’s roofs are a palimpsest: on the original concrete slab lies a layer of roofing felt, topped with corrugated metal, alongside a wooden extension structure covered with whatever was at hand—asbestos sheets, plastic, old doors.
“Nobody here asks if something complies with regulations. The question is: will it survive the next hurricane”—says one neighborhood resident, standing on a tenement roof on Calle Neptuno.
Style? More Like a Survival Strategy
It’s hard to talk about architectural style in the traditional sense. Centro Habana doesn’t have a unified aesthetic—it has an aesthetic of necessity. But look closely, and patterns begin to emerge. This isn’t chaos—it’s a system built on local conditions and constraints.
Flat Roofs as Foundation
Most buildings have reinforced concrete slabs designed as usable roofs. In a climate without snow, it’s a logical solution: flat surfaces serve for drying laundry, raising pigeons, neighborhood gatherings. The problem is that concrete ages, waterproofing fails, and water finds its way inside. That’s why new layers appear on old slabs—sometimes additional coats of tar paper, sometimes entirely new roof structures.
Additions as Expansion
When a family grows and moving isn’t an option, the only direction is up. Extra rooms sprout on rooftops—made of wood, concrete blocks, metal sheets. Their roofs are gabled or shed-style, because water must run off and materials are light. This isn’t designed architecture—it’s architecture negotiated with gravity and wind.
Materials as Historical Record
Corrugated metal from the ’90s, wood salvaged from old furniture, asbestos cement from pre-revolution times. Every roof is a chronicle of availability. Centro Habana has no building supply stores in the European sense—there are markets, exchanges, imports from family in the USA. You build a roof with what’s available, not what should be.
Why It Works — and Why It Sometimes Doesn’t
Improvisation has its advantages. Above all — it allows for quick response. When a roof leaks, repairs don’t wait for permits or estimates. Residents take what they have and patch it up. Structures are lightweight, so they don’t burden old walls. Materials are diverse, which paradoxically increases system resilience — if one element fails, another replaces it.
But this method has its limits. Lack of coordination means lack of accountability — when a roof from an upper floor leaks onto lower levels, conflict is inevitable. Lack of thermal insulation means infernal heat in add-ons during summer. And lack of ventilation and moisture management leads to mold growth that destroys wood and threatens health.
“The worst part isn’t that the roof leaks. The worst part is you don’t know who fixed it last or what’s actually up there” — says a woman living on the fourth floor of a tenement on Calle San Rafael.
Climate as Co-Author
Havana has a tropical climate — hot, humid, with intense rainfall and periodic hurricanes. Roofs must drain water but also withstand winds exceeding 150 km/h. That’s why structures are low-profile, fastening makeshift, and weight often replaces screws. These are solutions that wouldn’t pass any certification, but in most cases — they simply work.
Who This Model Is For — and What We Can Learn
Centro Habana isn’t a model to replicate literally. No one consciously chooses to live in a building that might collapse. But there’s something worth seeing here: flexibility. The ability to build without instructions. The capacity to adapt under extreme constraints.
In Europe, we talk about sustainable construction, recycling, low-budget architecture. Centro Habana has been doing all of this for decades — not by choice, but by necessity. Houses here aren’t designed for 50 years — they’re repaired every season, expanded every generation, modified for new needs. It’s living, organic, unstable architecture — but precisely because of that, enduring.
What You Can Apply to Your Own Project
Of course, no one should build without plans and permits. But several principles from Centro Habana have universal value:
- Lightweight roof structures — when a building is old or the ground unstable, every kilogram matters. Roofs made of wood and metal can be just as durable as concrete ones, and far easier to repair.
- Functional flexibility — a roof that can serve as a terrace, drying area, vegetable garden is a roof fully utilized. In a frost-free climate this is obvious, but in Europe too we’re increasingly thinking of roofs as usable space.
- Material recycling — not every element needs to be new. Salvaged timber, metal from a neighbor’s renovation, old windows as wall elements — this isn’t just savings, but history built into the structure.
- Adaptability — houses that can be easily modified are more resilient to changes — family, economic, climatic. Centro Habana shows that rigid designs aren’t always the most durable.
The Point: Architecture Without Guarantees, But With Meaning
Centro Habana’s roofs aren’t beautiful in the way we know from design magazines. They’re not safe by European code standards either. But they’re real. They’re the result of actual needs, real constraints, and daily decisions by people who don’t have time for aesthetic debates because they simply need to live.
This isn’t a defense of chaos. Rather, it’s a reminder that residential architecture — especially single-family, intimate, local — doesn’t have to be perfect to be effective. That sometimes the meaning of form lies not in the design, but in the process. And that the best solutions are those that let people live — even if the roof leaks occasionally.
Rooffers promotes informed decisions, durability, and responsibility in building. But it also promotes looking broader — at how people worldwide solve the problem of shelter. Centro Habana is one such place. Without certificates, but with a lesson you won’t find in any manual.
